“ Six years previously, Miss Brodie had led her new class into the garden for a history lesson underneath the big elm. On the way through the school corridors they passed the headmistress's study. The door was wide open, the room was empty.'Little girls,' said Miss Brodie, 'come and observe this.'They clustered round the open door while she pointed to a large poster pinned with drawing-pins on the opposite wall within the room. It depicted a man's big face. Underneath were the words 'Safety First'.'This is Stanley Baldwin who got in as Prime Minister and got out again ere long,' said Miss Brodie.
